The vga is the Sapphire VaporX version, and its running on 1100Mhz. I have Corsair TX650 v2 power supply. GTA5 and F1 2015 working perfectly. Now I installed a non Crimson driver, the 15.7.1 catalyst, and with this its perfect. So all of the newer drivers has a bug, and the AMD cant solve the problem. I need to use a 1 year old driver to play NFS....nice.
